A vigorous atmospheric disturbance skirted across western Colorado, using monsoon<\/span> moisture to fuel scattered<\/span> to widespread<\/span> thunderstorm activity for most areas except for the Northeast Plains. The first wave of thunderstorms began shortly after noon in the Southeast Plains and Northwest Slope. By mid-afternoon, heavy rainfall was being reported over many locales. Some of the more impressive 24-hour totals were 2.75 inches in Bent County, 1.14 inches in Pueblo County and just under 1 inch in Routt County (an observer reported about 0.35 inches in 15 minutes falling near Steamboat Springs). A long list of counties saw very short-term heavy rainfall that amounted to anywhere between 0.5 to 0.9 inches. A flash flood<\/span> report came in from Cheyenne County around 5PM, as water was flowing over a road.<\/p>\n A second wave of thunderstorms developed over the Southwest Slope where short-term heavy rainfall was noted, along with 1 inch hail and even several funnel reports. A flash flood<\/span> report was received from Dolores County where up to 2 inches of rainfall may have fallen over a very localized area. A separate wave of storms developed over the Southeast Mountains, and moved eastward producing heavy rainfall over a 15-30 minute period of time.<\/p>\n In all, about 14 warnings and advisories were issued by the National Weather Service offices covering the state. Of these, all but one were flash flood<\/span> \/ flood related. Certainly another busy weather day across our state.<\/p>\n For an estimate of 24-hour rainfall that occurred in your area, please check out our radar based map below. Note that because a radar’s beam cannot penetrate through mountainous terrain, rainfall amounts in the Flat Top, Park and Gore mountain ranges may be underestimated.<\/p>\n
